摘要：

The effect of heat treatment on microstructure development in Ba2YCu3O7_x films prepared from metal trifluoroacetate precursors is investigated. The growth of textured Ba2YCu3O7_xon BaZr03 substrates is shown to be strongly influenced by the furnace atmosphere used during calcination. Differential thermal analysis was used to show that conditions that promote c-axis texture are also those which cause partial melting of Ba-Y-Cu-O compositions that are depleted in barium relative to Ba2YCu307-x. © 1990, Materials Research Society.
